fix(profiling): clear heap profiler states after fork #16257

taegyunkim · 2026-01-29T04:52:51Z

Description

Clears heap profiler states after fork via pthread_atfork.

This addresses a crashes that happen when using libdatadog's interning API, which was introduced to 4.3.0 via #15062 and reverted by #16243.

The bug happens as

Upon fork, the child fork handlers are executed in the order they're registered (ref: pthread_atfork.3#RETURN_VALUE)
- fork handlers from ddup (Profiler.__init__() -> _ProfilerInstance.__init__() -> _ProfilerInstance.__post_init__() -> _ProfilerInstance._build_default_exporters() -> ddup.start() -> ddup_start())
- fork handlers from Profiler's start which call Profiler.restart_on_fork, registered through our forksafe.register (Profiler.start() -> forksafe.register(self._restart_on_fork()))
The first (ddup) fork handler would release the ProfilesDictionary (utility from libdatadog used for string interning)
The second (forksafe) fork handler would try to stop the memalloc Memory Profiler

However, given that forksafe-registered handlers are Python functions (and thus execute Python code), they interact with the CPython state and may allocate or de-allocate memory. As at that point, the Memory Profiler is still running according to its state variables (nothing stopped it before that very fork handler whose job it is to stop it), it could try to write a Sample, by which libdatadog would try to "render" the interned strings, thus trying to access memory belonging to the freed ProfilesDictionary ⇒ segmentation fault.

Testing

This PR has interning and the reproducer as a unit test: perf(profiling): re-add interning #16276
